A potential stage based on Super Mario Land was considered for the Nintendo 3DS version to represent the Game Boy. However, a stage based on Kirby's Dream Land was used instead for unknown reasons (the stage was renamed to Dream Land GB in Super Smash Bros. Ultimate to avoid confusion with another stage already named Dream Land).

A reversal of this kind also happened in the Wii U version, where a stage based on Kirby's Epic Yarn was considered, but was revamped into a stage based on The Great Cave Offensive from Kirby Super Star after the development team heard about the then-upcoming Wii U game Yoshi's Woolly World.
